SNAPPING AND HUSKING ROLL Application filed June 14,

relates to improvements .in

corn husking machines and particularly to the snapping and hashing rolls of such machines.

One oi the main faults to be overcome in the construction of these rolls is to prevent the shelling of the corn being operated upon and one of the objects of this invention is to provide snappingand husking rolls that will shell but little, it any, of the corn, thus making the machine especially adaptable for use in connection with husking seed corn.

it has also been the practice, heretofore, in

porn husking machine construction to mount on the huslzing rolls, rows of pins that projcct beyond the peripheries of the rolls, thus rendering it necessary to form slots or grooves in the adjacent cooperating rolls and time the several rolls so that the projecting end portions of the pins carried by one roll will register with and enter said slots or grooves in the adjacent roll. A further object of this invention is, therefore, to provide a husking roll wherein the pins terminate substantially flush with theperipheries of the rolls, thereby eliminating the use of coop-rating slots in the adjacent rolls and eliminating, also, the timing of the rolls.

In the accompanying drawings- Figure l. is a perspective view of a husking roll en'ibodying the present invention;

Fig. 9 is a sectional view through two adjacent husking rolls; and

Fig. I; is a perspective view of roll.

The bushing and snapping rolls 10 can be made of any suitable material but they are preferably made in half section castings, the two sections being secured together by bolts 20. it its ends the roll is provided with shafts 11 which are turned down to the proper diameter to be accommodated by the bearings in the bushing machine frame.

iiormed in the rolls 10 are a plurality,

usually two, longitudinally extending grooves 12 and as is understood, it isthe abrupt iongitudinally extending side edges 13 of the grooves in the snapping rolls that sever the ears of corn from thestalks between the rolls. Usually, however, in former cases, the grooves in the snapping rolls have been made comparatively deep to provide a deep bralier and thecarsot corn would be drawn into the grooves with the result that considerable corn would be shelled oh? the cob. To overcomethis, there is provided in the presentcase, means for preventing the entering the grooves 12 to any appreciable extent. These means preferably consist in forming the grooves with a raised bottom portion 14: extending the length of the groove and in order to ob tain a deep braker said raised portion 141 is spaced from the sides 13 of the grooves, thus leaving the comparatively deep braker recesses 15 at each side of the groove. The raised portion 14:, of course, does not extend up to the periphery of the roll and it may either be broken at intervals along the roll or it may be made continuous. lVith snapping rolls of this construction it will be found that the ears of corn will be efficiently snapped or broken from the stalks and but little, if any, of the corn shelled.

The same form of groove 12 is used in the rolls utilized for husking the ears of corn after they have been removed from the stalk but, as is well known in the art, these husking rolls are each provided with one or more longitudinally extending series of husking pins 16 as shown in Figs. 1 and 2. The raised bottoms 1 of the husking rolls serve the same purpose in these rolls as they do in the snapping rolls, i. e., they prevent shelling of the corn.

In the case of bushing rolls, however, this invention further contemplates the provision of a huslcing roll that will permit the use of a series of juxtaposed rolls without the necessity of rotating the rolls in timed relation to insure the pins 16 in one roll always registering with a cooperating groove in an adjacent roll. This is conveniently and preferably accomplished by mounting the rows of pins 16 in the raised bottom portions 14 of the grooves 12, the outer ends of said pins lying immediately below or substantially flush with the periphery of the roll. The cars of corn can enter, to a slight extent, the grooves 12, due to the raised portions 14 lying somewhat below the periphery of the rolls and the pins 16 will tear the husks from the ears but as the entrance of the ears into the grooves is limited by the raised bottoms 14: none of the corn will be shelled.

Furthermore, as the pins 16 do not pro jectbeyond the peripheries of the rolls it is unnecessary to provide recesses or grooves in one roll to accommodate the pins of an adjacent roll and it is also unnecessary to provide for the timing of the rotating rolls. The absence of projecting pins and the consequent elimination of grooves for the reception of such projecting pins or, in other Words, the reduction in the number of grooves other than those having pins mounted therein, tends to reduce injury to the grains as well as to lessen shelling of the corn.

that is claimed is:

1. A husking roll for corn husking machines'having a longitudinally extending groove therein, a longitudinally extending raise-d portion in the bottom of said groove,

@ said raised portion lying below the periphery of the roll, and a series of husking pins mounted in said groove.

2. A husking roll for corn husking machines having a longitudinally extending groove therein, said groove having a raised bottom portion, and a series of husking pins mounted in said raised portion, said pins terminating substantially flush with the periphery of the roll.

3. In a corn husking machine, the combination of a pair of juxtaposed husking rolls, there being a plurality of longitudinally extending grooves in each roll, each of said grooves having a raised bottom portion, husking pins mounted in the grooves and terminating substantially flush with the peripheries of the rolls and the grooves and pins of oneroll being staggered with respect to the grooves'and pins of the other roll.

'4. In a. corn husking machine, the combination of a pair of juxtaposed husking rolls each having a plurality of grooves therein, each of said grooves having a raised bottom, and a row of husking pins mounted in each of said grooves, said pins terminating substantially flush With the peripheries of the rolls.
